<p>The horizontal cutter-blade is fixed behind the verticaly-suspended cutter-blade and can overlap each other. The cutter-unit is fixed on a tilting section. Both blades are driven by means of two eccentric rods fixed to the two ends of a shaft. The angular displacement of the two blades is pref. one hundred and seventy degrees. The angle of the vertical blade to the horizontal blade can be adjusted mechanically from the driving seat, by means of a lever. The width can be adjusted manually by means of two screws or electrically by remote control. A single-acting lifting cylinder regulates the height and is rigidly fixed to a chassis on the tractor. The cylinder piston is fixed in two C-shaped rails. The eccentric shaft is pref. driven by means of a cone-belt, and a motor with volume distributor.</p> |
